JAMES FARNAN, OF CLEVELAND, OHIO.

IMPROVEMENT IN HVDRANTS AND STREET`WASHERS.

Specification forming part of Letters Patent No. l31,512, datedSeptember 24, 1872.

To all whom it may concern:

Be it known that I, JAMES FARNAN, of Cleveland, in the county ofCuyahoga and State of Ohio,haveinvented a certain new and ImprovedHydrant; and I do hereby declare that the following is a full, clear,and complete description thereof, reference being had to theaccompanying drawing making -part of the same.

Figure lis an outside view of the hydrant. Fig. 2 is a transversevertical section. Fig. 3 is a view of the inside from the top.

Like letters refer to like parts in the several views. Y

The nature of this invention relates to a hydrant; and the object ofwhich is to so construct an upper chamber and draft-pipe of said hydrantthat it shall be in one piece instead of iu two pieces. It also relatesto the manner of attaching the shaft or' box to the connecting-pipe ofthe hydrant, the same being an improvement of a hydrant for which apatent vsavs1 granted to me on the 11th day of April,

Of the above said invention the following isa more full and completedescription:

In the drawing, Fig. 1, A represents a pipe connecting the upper andlower parts of the hydrant to each other. Said lower part consists of ashell, B, screwed to the lower end of the pipe A, as seen in Fig. 2. Thebottom of the shell forms a seat for the valve C, and down upon which itis represented as being forced by the screw D, seen at the upper end ofthe rod E. Within the shell B is an annular chamber, F, Fig. 42, inwhich is fitted a plug, C', to the end of which the valve is secured;thepurpose ofsaidplug will presentlybe shown. It will be observed onexamination of Fig. 2 that said annular chamber F does not ill theentire capacity of the shell; but between which and the wall of theshell is a space, c. From the annular chamber referred to proceeds ashort tube, b, through to the outside of the shell B, the object ofwhich is to allow the water to escape from the hydrant, as and forapurpose hereinafter shown. E is a rod u connecting the valve C to thescrew D. Said screw is tted in a nut, J, and the shank J passes througha stalling-box, K, whereby it is made tight. The nut J referred to isscrewed into a cylinder, L, whereas the lower'end of the shell issecured to thepipe A by being screwed thereon, as shown in Fig. 2. M isa pipe, from which the water flows out of the hydrant, and to which maybe attached a water-cock, hose, &c. N is a case or box inclosing all theupper parts of the apparatus.

The practical operation of the above-described hydrant is as follows:The lower part thereof is buriedfin the ground at a depth below thereach of frost, and which depth may be made more or less by using acorresponding length of pipe, A, and rod E, whereas the upper part isnear to or at the surface, so as to be of easy access, and which beinginclosed by the shell or chamber N, can be at all times reached onlifting the cover N. The lower end'of the apparatus'is connected to thewatermain by a pipe in the ordinary way. Fig. 2 represents the valve Gas closed, thereby shutting off the water, but which may be opened onapplying a key to the end or stem J On turning it in the properdirection the valve is raised and the water flows in and up around theannular chamber F, thence through the pipe A, and is discharged from thenozzle of the pipe N to the outside. On shutting oif the water, all thatmay be in the hydrant above the valve would remain therein, unless someavenue for its escape were provided. This provision for such escapeconsists of the short tube b, referred to, and which, as above said,opens the annular chamber F to the outside, from which all the waterabove the valve can run out when the valve is closed, but which cannotescape therefrom when the valve is open, as the plug C rises up andcovers the aperture on the inside on lifting the valve. By thus allowingthe water to escape from the hydrant through the waste-pipe b is avoidedthe danger of freezing 5 hence the hydrant remains in working order atall times.

It will be observed that the diameter of the valve and plug is aboutthat of the pipe A; hence, in the event that a new valve, &c., may berequired, it can be easily supplied by withdrawing the valve and plug upthrough the pipe to the outside for necessary repairs, &c.

In my former hydrant the cylinder L and the discharge-pipe M consistedof two pieces; the pipe beingconnected to the cylinder by a screwjoint,the labor and expense of which added much to the cost of the hydrant.

In this hydrant the cylinder and pipe are made in one piece with muchless labor and eX- pense of construction; it is also much stronger,

simpler, and not liable to leak. In this hydrant the case or box N isattached to the pipeA by a collar, O, forming a part of the box, and inwhich is a set-screw, whereby the collar is made fast to the pipeinstead of being screwed thereto by a thread in the collar fitting onthe pipe in the character of a screw-nut.

Claim.

What I claim as my invention, and desire to secure by Letters Patent,is-

The hydrant or street-Washer with a cylinder, L, and pipe M, asdescribed, in combination with the pipe A, stem E, and shell N,substantially as and for the purpose set forth.
